WATER-HEATER.

Specification of Letters Patent.

Patented June 5, 1906.

Application led January 31, 1906. Serial No. 298,847.

To ctZZ whom t may concern:

Be it known that I, JOI-IN K. MOLAUGHLIN, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Water-Heater, of which the following is a specification.

My present invention relates to watern heaters; and it consists of a novel construction of a heater unit in which the water or circulating fluid passing therethrough is always in contact with a heated surface.

It further consists of a novel construction of a unit composed of an upper and lower member having interposed therebetween a suitable diaphragm having a baffle-plate on opposite sides of said diaphragm and engaging the contiguous side of its outer disk member and novel means for leading the fluid to be heated into and out of the chambers formed between said diaphragm and the upper and lower disk members ofthe unit.

It further consists of a novel construction of a unit in which the circulating fluid is always exposed to a heated surface, and in addition this unit has passages therethrough, through which pass the flame and products of combustion.

It further consists of a novel construction of coupling connection suitably secured to the intermediate disk or diaphragm member whereby the units may be correlated and arranged according to the conditions and requirements and the circulating fluid may readily pass from one unit to the next unit in the series.

It further consists of novel features of construction, all as will be hereinafter fully set forth.

Figure 1 represents a perspective view of a fluid-heating unit embodying my invention, the same being viewed from its under side, but having a portion of the lower disk-casing removed. Fig. 2 represents a perspective view viewed fromabove, but having a portion of the upper disk-casing removed for convenience of illustration. Fig. 3 represents a sectional view of one of the units. Fig. 4 represents a top plan view of a portion of a unit having the upper disk-casing removed. Fig. 5 represents a sectional elevation showing one manner in which the units may be arranged in a water-heater.

Similar numerals of reference indicate cor- 5 responding parts in the figures.

heater unit or section, the same being provided with an upper casing or disk 2 and a lower casing or disk 3, said upper disk having a laterally-extending flange 4, which abuts against a flange 5, which latterextends angularly from a flange 6, extending laterally from the lower disk 3.

-7 designates a diaphragm or dividing member the outer perimeter of which .is seated between the flange 4 of the upper member 2 and the flange 6 of the lower member 3 and abutting against the flange 5, whereby a tight joint may be readily formed between the upper and lower members.

8 designates a threaded connection or coupling secured to the disk or diaphragm 7 by means of a bolt 9 and a nut 10 or equivalent devices.

11 designates a threaded connection of a similar character to the connection S and suitably secured to the opposite side of the intermediate member 7. The connection 8 is provided with a suitable shoulder 12, and the disk 2 is centrally apertured in order that when the parts are in assembled position said upper disk will abut against the shoulder 12 and have water-tight connection therewith. The lower connection 11 is provided with a similar shoulder 13, against which abuts the lower disk member 3 when the parts are in assembled position, said lower member 3 having a suitable aperture therethrough, whereby it may be readily placed in position on said connection or coupling. These connections may be squared or otherwise adapted to receive a suitable wrench, whereby the units may be readily connected or disconnected from the heating system, as desired.

14 designates a baffle-plate extending from the connection 11 and adapted to form a water-tight connection between the disk 7 and the lower disk 3. The circulating fluid passes through the inlet 15 into the connection 11 and is thence defiected through an opening 16, which is in proximity to or contiguous to the bafile-plate 14, which causes the fluid to be deflected and pass around the chamber formed between the center diaphragm 7 and the lower disk 3, thence through an opening 17 in the diaphragm 7, which is contiguous to the baffle-plate 14.

18 designates a baHie-plate similar to the baffle-plate 14 and forming a water-tight erigagement between the connection 8, the diaphragm 7, and the upper disk 2 in a similar manner to that already described. The wa- IOO IIO

f the scope of my invention.

ter passing through the opening 17 is deiiected by the bathe-plate 18 and passes around the chamber formed between the uppermember 2 and the diaphragm 7 in the direction of the arrows until it strikes the opposite side of said baHie-plate 18 and is deiiected thereby through an opening 19 in the coupling connection 8. In order to increase the heatingsurface of the unit, the upper disk member 2 is suitably apertured, as at 20, vand the'lower disk member is apertured in a like manner, as at 21. The diaphragm 7 has suitable apertures 22 extending therethrough. These apertures 20, 21, and -22 are in alinement when the parts arein assembled position and have secured therein a suitable tube or pipe 23, which is provided at each end with a shoulder 24, whereby a water-tight connection may be Jformed between the central diaphragm and the upper and lower disk members.

In Fig. 5 I have shown in sectional elevation one manner in which the heater sections or units may be arranged, although it will be apparent that said sections may be otherwise correlated and arranged and still be within In this gure, 25 designates a burner or heating medium, which may be of any usual or conventional type, said burner being suitably supported on a bottom casing 26, to'which is attached an outer casing 27.

28 designates a diaphragm or closure supported at the upper end of the outer casing 27 and having an opening 29 therethrough.

30 designates the top of the casing, having a suitable opening 31 therethrough.

The operation will be readily apparent and is as follows: The water or other fluid which it is desired to heat enters through the pipe 32, and passes through the inlet 15 into the chamber 33 of the lower connection of the iirst heating section, to which the pipe 32 is secured. The water then passes through the opening 16 into the chamber formed between the diaphragm l7 and the lower disk 3. It then passes around said chamber in the direction of the arrows (seen' in Fig. 1) until ity strikes the baffle-plate 14 and is deflected thereby, through the opening |17, into the chamber formed between the upper disk 2 and the diaphragm 7. In this chamber it is deiiected by the baHie-plate 18 and passes around the chamber formed between the diaphragm 7 and the upper disk member 2 until it strikes the opposite side of said barile-plate and is deflected thereby, through the opening 19, into vthe chamber 34 and thence through the outlet 39 into the pipe 35. The water passes from this connection 35 to the second heating section or unit, through which the water circulates in the same manner as that already described in connection with the i'irst unit.

36 designates a pipe leading from the last heating unit, said pipe being suitably con- `result would be obtained.

nected, by means of a coupling-nut or equivalent device 37, with the distribution-pipe 38, by means of which the heated water is conducted to a desired point of utilization. The products of combustion surround on all sides the different units and also pass through the tubes 23 and escape at the top of the heater through the ports or openings 29 and 3 1.

It will thus be seen that in my present construction the heated products of combustion not only completely surround the units, but also pass therethrough, and the water or other fluid passing through the heater will always be exposed to a heated surface, so that the water or other iiuid will be rapidly heated in a very eHicient, cheap, and reliable manner. Since each heating unit will absorb the heat in proportion to the amount of the exposed surface, it will be evident that by increasing the heating-surface the e'Hiciency of the unit is greatly increased.

It'will be further apparent that the unit may be very cheaply constructed and is in a very compact form when the parts are in assembled position and, further, that the units may be correlated and arranged in any desired manner, according to the results which it is desired to attain and the condition and requirements of the case.

It will be further apparent that while in the present instance for convenience of illustration I have shown the coupling member as composed oi' two parts 8 and 11 and the intermediate diaphragm 7 as extending between these two coupling -membcrs this coupling member may be formed of a single piece of material having an intermediate diaphragm therein, in which case the diaphragm, as 7, would extend only to the walls of the coupling and the water would pass through the unit in the same manner and the same I do not, therefore, desire to be limited to the construction 'in which the coupling is composed of two parts having the intermediate diaphragm passing therethrough.
